Description of Related Art

With frequent commercial activities and the rapid expansion oftransportation logistics, people are more dependent on the mobilevehicle such as car or motorcycle. At the same time, drivers are payingmore and more attention to the protection of their lives and propertywhen driving, and therefore, in addition to the performance and thecomfort of the mobile vehicle, it is also considered whether the mobilevehicle to be purchased provides sufficient safety guards or auxiliarydevices. Under this trend, in order to increase the safety of vehicles,automobile manufacturers or vehicle equipment design manufacturers havedeveloped various driving safety protection devices or auxiliarydevices, such as rearview mirrors, driving recorders, a panoramic imageinstant displaying of blind vision areas, a global positioning systemthat records the driving path at any time, and etc.

In addition, with the rapid development of digital cameras and computervisions in daily life, the digital cameras have been applied to drivingassistance systems, hoping to reduce the accident rate of trafficaccidents through the application of artificial intelligence.

The driver's visual angle changes with the speed of the vehicle,external environmental factors (such as weather, brightness, vehicleconditions), and physiological conditions during driving, making itdifficult for the driver to notice the signs on the road, resulting inmiss or misinterpret the signs on the road. Especially when changinglanes, the driver should pay attention to the surrounding environment atthe same time, thereby it is hard to notice the signs on the road.

Therefore, there is a need for the manufacturers to develop an auxiliarysystem which could accurately detect the signs on the road, improvingthe driving safety.

The length of the contour curve of any surface of a single lens in therange of the maximum effective radius affects the surface correctionaberration and the optical path difference between the fields of view.The longer the profile curve length, the better the ability to correctthe aberration, but at the same time It will increase the difficulty inmanufacturing, so it is necessary to control the length of the profilecurve of any surface of a single lens within the maximum effectiveradius, in particular to control the profile length (ARS) and thesurface within the maximum effective radius of the surface. Theproportional relationship (ARS/TP) between the thicknesses (TP) of thelens on the optical axis. For example, the length of the contour curveof the maximum effective radius of the side surface of the first lensobject is represented by ARS11, and the thickness of the first lens onthe optical axis is TP1, and the ratio between the two is ARS11/TP1, andthe maximum effective radius of the side of the first lens image side.The length of the contour curve is represented by ARS12, and the ratiobetween it and TP1 is ARS12/TP1.

For any surface of any lens, the profile curve length within a half theentrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half the entrance pupil diameter (HEP) of one surface andthe thickness (TP) of the lens, which the surface belonged to, on theoptical axis (i.e., ARE/TP) has to be particularly controlled.

The profile curve length of a half theentrance pupil diameter (HEP) of the object-side surface of the secondlens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of half the entrance pupil diameter(HEP) thereof and the thickness of the lens which the surface belongedto is denoted in the same manner.

DETAILED DESCRIPTION OF THE INVENTION

A movable carrier auxiliary system of the present invention mainlyincludes a system design and an optical design, wherein systemembodiments will be described first.

Take FIG. 1A and FIG. 1B as an example to illustrate a schematic view ofa movable carrier auxiliary system 0001 according to a first systemembodiment of the present invention applied to a movable carrier 0000(e.g. a vehicle). In the current embodiment, the movable carrierauxiliary system 0001 at least includes a sign detecting device 0010,wherein the sign detecting device 0010 includes an image capturingmodule 0011, a storage module 0012, and an operation module 0013. Theimage capturing module 0011 is disposed on the movable carrier 0000 forcapturing an environment image around the movable carrier 0000. In thecurrent embodiment, the image capturing module 0011 is disposed on afront side of the movable carrier 0000 and is adapted to capture andgenerate the environment image which is in front of the movable carrier0000. The front side of the movable carrier 0000 could be, for example,a side of a head of a vehicle, a vicinity of the front windshield insidethe vehicle, or a side of the front bumper. Preferably, the imagecapturing module 0011 is disposed on a geometric center line i of thebody of the movable carrier 0000, for example, at a center of thevehicle body in the lateral direction. The image capturing module 0011includes a lens group and an image sensing component, and the lens groupincludes at least two lenses having refractive power for imaging to theimage sensing component to generate the environment image. A horizontalview angle of the environment image is at least 45 degrees. Theconditions of the lens group will be described in the opticalembodiments.

The storage module 0012 stores a plurality of sign models and aplurality of action modes corresponding to the sign models. Theoperation module 0013 electrically connected to the image capturingmodule 0011 and the storage module 0012 for detecting whether theenvironment image has a sign image that matches at least one of the signmodels, and correspondingly generating a detection signal, wherein thesign image could be, for example, traffic signs, traffic symbols, or asign on another vehicle (e.g. a brake light, an indicator light, areversing light). As shown in FIG. 1B, the two signs are respectively atraffic light 000A and a speed sign 000B.

In the current embodiment, the sign detecting device 0010 furtherincludes a luminance sensor 0014 electrically connected to the imagecapturing module 0011 for detecting the luminance on at least thedirection in which the image capturing module 0011 captures the image.When the luminance measured by the luminance sensor 0014 is greater thanan upper threshold, the image capturing module 0011 captures theenvironment image in a way that reduces amount of light entering. Whenthe luminance measured by the luminance sensor 0014 is less than a lowerthreshold, the image capturing module 0011 captures the environmentimage in a way that increases the amount of light entering. In this way,an environment image with appropriate luminance could be obtained,avoiding overexposure or underexposure.

In the current embodiment, the movable carrier auxiliary system 0001further includes a control device 0020 disposed on the movable carrier0000 and is electrically connected to the operation module 0013 and thestorage module 0012. The control device 0020 is adapted tocorrespondingly control the movable carrier 0000 to operate based on oneof the action modes corresponding to the matching sign model when thecontrol device 0020 receives a detection signal that the environmentalimage has a sign image matching at least one of the sign models. Forexample, the control device 0020 could control the movable carrier 0000to slow down, to brake, to speed up, etc.

Different controls could be carried out depending on different movementstates of the movable carrier 0000. The movable carrier auxiliary system0001 further includes a state detecting device 0021 disposed on themovable carrier 0000 and electrically connected to the control device0020 for detecting a movement state of the movable carrier 0000 andgenerating a state signal. In practice, the state detecting device 0021could include at least one of a steering angle sensor, an inertiameasuring device, and a speed sensor, wherein the steering angle sensordetects a steering angle of the movable carrier 0000; the inertiameasuring device is adapted to detect an acceleration, an inclinedangle, or a yaw rate of the movable carrier 0000; the speed sensor isadapted to detect a speed of the movable carrier 0000. The statedetecting device 0021 correspondingly outputs the state signal based ona detecting result of at least one of the speed sensor, the inertiameasuring device, and the steering angle sensor.

When the control device 0020 receives a detection signal that theenvironmental image has a sign image matching at least one of the signmodels, the control device 0020 controls the movable carrier 0000 tooperate based on the state signal and one of the action modescorresponding to the matching sign model. For instance, the controldevice 0020 correspondingly controls the movable carrier 0000 based onone of the action modes of automatic driving and the state signal of acurrent moving speed, preventing the person in the movable carrier 0000feels uncomfortable due to the action mode switches.

As shown in FIG. 1C, in the current embodiment, the operation module0013 could detect a distance between the movable carrier 0000 and atleast one sign based on the environmental image, and detect a positionof the at least one sign in the environmental image, and correspondinglygenerate the detection signal. For example, when the control device 0020receives a detection signal that the distance between the movablecarrier 0000 and the sign image matching at least one of the sign modelsis less than a safe distance, the control device 0020 controls themovable carrier 0000 in an action mode that slowing the speed of themovable carrier 0000 (e.g. the control device 0020 controls the movablecarrier 0000 to slow down by braking or decelerating, or etc.).

In practice, the image capturing modules 0011 could include two imagecapturing modules 0011 for capturing the environment images withdifferent depth of fields. The operation module 0013 detects whether athree-dimensional environment image formed by the environment imagescaptured by the two image capturing modules 0011 has a sign image thatmatches at least one of the sign models, and detects a distance betweenthe movable carrier 0000 and the sign image matching at least one of thesign models, and correspondingly generates the detection signal.

In addition to detecting the sign image via the environment image, thesign detecting device 0010 further includes a detection wave transceivermodule 0015 electrically connected to the operation module 0013. Thedetection wave transceiver module 0015 sends a detection wave on atleast the direction in which the image capturing module 0011 capturesthe image (e.g. a direction in front of the movable carrier 0000), andreceives the reflection detection wave of the detection wave, whereinthe detection wave could be ultrasonic wave, millimeter wave radar,lidar, infrared light, laser, or a combination of the foregoing. Theoperation module 0013 further detects a contour of objects within thedirection in which the image capturing module 0011 captures the image bythe reflection detection wave. The operation module 0013 analyzeswhether the environmental image has a sign image that matches at leastone of the sign models by comparing and matching at least one of thecontours of the objects with the sign models, and correspondinglygenerates the detection signal, thereby to determine a correctness ofthe detected sign image via the environmental image and the reflectiondetection wave.

In addition, the detection wave could further detect the distancebetween the movable carrier 0000 and the detected sign image, thereby todetermine correctness of the safe distance via the environmental imageand the reflection detection wave.

In order to generate a warning of the detected sign image, the movablecarrier auxiliary system 0001 further includes a warning module 0022electrically connected to the operation module 0013, the storage module0012, and the state detecting device 0021. In addition, the storagemodule 0012 further stores a plurality of state limitationscorresponding to the sign models, wherein the state limitations couldbe, for example, a speed limit of 60 Km/h, no right turn, etc.

The warning module 0022 reads at least one of the state limitations inthe detection signal corresponding to the matching sign model from thestorage module 0012 when the warning module 0022 receives the detectionsignal and state signal of the movable carrier 0000, and generates awarning message when the movement state of the movable carrier 0000 doesnot in accordance with at least one of the state limitations. Forexample, the warning module 0022 generates the warning message when asign that speed limit of 60 Km/h is detected and the movement state ofthe movable carrier 0000 is that the speed of the movable carrier 0000exceeds 60 Km/h which is not in accordance with the state limitation(i.e., speed limit of 60 Km/h). For example, the warning module 0022generates the warning message when a sign that no right turn is detectedand the movement state of the movable carrier 0000 is that the movablecarrier 0000 turns right which is not in accordance with the statelimitation (i.e., no right turn).

In order to prompt the driver, the movable carrier auxiliary system 0001further includes a warning member 0023 electrically connected to thewarning module 0022 and a displaying device 0024, wherein the warningmember 0023 is adapted to receive the warning message and tocorrespondingly generate at least one of light and sound when thewarning module 0022 sends the warning message. For example, generate awarning of light or sound when drives above the speed limit or whenturns in a situation that turning is prohibited. The warning member 0023includes a buzzer or/and a light emitting diode (LED), which can berespectively disposed at the left and right sides of the movable carrier0000 (e.g. an inner or outer area near the driver seat of the movablecarrier 0000, such as the front pillar, the left/right rear-view mirror,the fascia, the front windshield, etc.), so as to operate correspondingto the detection results of the movable carrier 0000.

The displaying device 0024 is adapted to display the warning message.For example, the warning message could be displayed on the displayingdevice 0024 as an image, a text, or both of the image and the text. Atleast one of the warning member 0023 and the displaying device 0024prompts the driver that the movable carrier 0000 is not in accordancewith the state limitation corresponding to the sign model.

FIG. 1D is a schematic perspective view showing the displaying device0024 according to the first system embodiment of the present invention,in which the displaying device 0024 is a vehicle electronic rear-viewmirror 0100 having a display (not shown), for example. FIG. 1E is aschematic section view taken along the short side of the displayingdevice of FIG. 1D. The vehicle electronic rear-view mirror 0100 could bedisposed on a movable carrier, e.g. a vehicle, to assist in the drivingof the vehicle or to provide information about driving. Morespecifically, the vehicle electronic rear-view mirror 0100 could be aninner rear-view mirror disposed inside the vehicle or an outer rear-viewmirror disposed outside the vehicle, both of which are used to assistthe driver in understanding the location of other vehicles. However,this is not a limitation on the present invention. In addition, themovable carrier is not limited to the vehicle, and could be other typesof transportation, such as a land train, an aircraft, a water ship, etc.

The vehicle electronic rear-view mirror 0100 is assembled in a casing0110, wherein the casing 0110 has an opening (not shown). Morespecifically, the opening of the casing 0110 overlaps with a reflectivelayer 0190 of the vehicle electronic rear-view mirror 0100 (as shown inFIG. 1D). In this way, external light could be transmitted to thereflective layer 0190 located inside the casing 0110 through theopening, so that the vehicle electronic rear-view mirror 0100 functionsas a mirror. When the driver drives the vehicle and faces the opening,for example, the driver could perceive the external light reflected bythe vehicle electronic rear-view mirror 0100, thereby knowing theposition of the rear vehicle.

Referring to FIG. 1E, the vehicle electronic rear-view mirror 0100includes a first transparent assembly 0120 and a second transparentassembly 0130, wherein the first transparent assembly 0120 faces thedriver, and the second transparent assembly 0130 is disposed on a sideaway from the driver. More specifically, the first transparent assembly0120 and the second transparent assembly 0130 are translucentsubstrates, wherein a material of the translucent substrates could beglass, for example. However, the material of the translucent substratesis not a limitation on the present invention. In other embodiments, thematerial of the translucent substrates could be plastic, quartz, PETsubstrate, or other applicable materials, wherein the PET substrate hasthe advantages of low cost, easy manufacture, and extremely thinness, inaddition to the packaging and protection effects.

In this embodiment, the first transparent assembly 0120 includes a firstincidence surface 0122 and a first exit surface 0124, wherein anincoming light image from the rear of the driver enters the firsttransparent assembly 0120 via the first incidence surface 0122, and isemitted via the first exit surface 0124. The second transparent assembly0130 includes a second incidence surface 0132 and a second exit surface0134, wherein the second incidence surface 0132 faces the first exitsurface 0124, and a gap is formed between the second incidence surface0132 and the first exit surface 0124 by an adhesive 0114. After beingemitted via the first exit surface 0124, the incoming light image entersthe second transparent assembly 0130 via the second incidence surface0132 and emitted via the second exit surface 0134.

An electro-optic medium layer 0140 is disposed in the gap between thefirst exit surface 0124 of the first transparent assembly 0120 and thesecond incidence surface 0132 of the second transparent assembly 0130.At least one transparent electrode 0150 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140. Theelectro-optic medium layer 0140 is disposed between the firsttransparent assembly 0120 and at least one reflective layer 0190. Atransparent conductive layer 0160 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140.Another transparent conductive layer 0160 is disposed between the secondtransparent assembly 0130 and the electro-optic medium layer 0140. Anelectrical connector 0170 is electrically connected to the transparentconductive layer 0160, and another electrical connector 0170 iselectrically connected to the transparent electrode 0150, which iselectrically connected to the electro-optic medium layer 0140 directlyor indirectly through the another transparent conductive layer 0160,thereby transmitting electrical energy to the electro-optic medium layer0140 to change a transparency of the electro-optic medium layer 0140.When a luminance of the incoming light image exceeds a certain luminance(e.g. strong light from the headlight of the rear vehicle), a glaresensor 0112 electrically connected to a control member 0180 receives thelight energy and convert it into a signal, and the control member 0180determines whether the luminance of the incoming light image exceeds apredetermined luminance, and if a glare is generated, the electricalenergy is provided to the electro-optic medium layer 0140 by theelectrical connector 0170 to generate an anti-glare performanceGenerally, if the incoming light image has a strong luminance, the glarecould be generated and thus affects the driver's line of sight, therebyendangering the driving safety.

In addition, the transparent electrode 0150 and the reflective layer0190 could respectively cover the entire surfaces of the firsttransparent assembly 0120 and the second transparent assembly 0130.However, this is not a limitation on the present invention. In thisembodiment, the transparent electrode 0150 could use a material selectedfrom metal oxides, such as indium tin oxide, indium zinc oxide, aluminumtin oxide, aluminum zinc oxide, indium antimony zinc oxide, or othersuitable oxides, or a stacked layer composed of at least two of theforegoing oxides. Moreover, the reflective layer 0190 could beconductive and made of a material selected from the group consisting ofsilver (Ag), copper (Cu), aluminum (Al), titanium (Ti), chromium (Cr),molybdenum (Mo), and an alloy thereof, or contains silicon dioxide or atransparent conductive material. However, the material of thetransparent electrode 0150 and the material of the reflective layer 0190are not limitations on the present invention. In other embodiments, thematerial of the transparent electrode 0150 and the material of thereflective layer 0190 could be other types of materials.

The electro-optic medium layer 0140 could be made of an organic materialor an inorganic material. However, this is not a limitation on thepresent invention. In the current embodiment, the electro-optic mediumlayer 0140 could be an electrochromic material. The electro-optic mediumlayer 0140 is disposed between the first transparent assembly 0120 andthe second transparent assembly 0130 and also disposed between the firsttransparent assembly 0120 and the reflective layer 0190. Morespecifically, the transparent electrode 0150 is disposed between thefirst transparent assembly 0120 and the electro-optic medium layer 0140(i.e., the electrochromic material layer). In an embodiment, thereflective layer 0190 could be disposed between the second transparentassembly 0130 and the electro-optic medium layer 0140. In addition, inthe current embodiment, the vehicle electronic rear-view mirror 0100further includes an adhesive 0114 located between the first transparentassembly 0120 and the second transparent assembly 0130 and surroundingthe electro-optic medium layer 0140. The electro-optic medium layer 0140is co-packaged by the adhesive 0114, the first transparent assembly0120, and the second transparent assembly 0130.

In the current embodiment, the transparent conductive layer 0160 isdisposed between the electro-optic medium layer 0140 and the reflectivelayer 0190. More specifically, the transparent conductive layer 0160could be used as an anti-oxidation layer of the reflective layer 0190,so that the electro-optic medium layer 0140 could be prevented fromdirect contact with the reflective layer 0190, thereby preventing thereflective layer 0190 from being corroded by the organic materials, andextending the service life of the vehicle electronic rear-view mirror0100 of the current embodiment. In addition, the electro-optic mediumlayer 0140 is co-packaged by the adhesive 0114, the transparentelectrode 0150, and the transparent conductive layer 0160. In thecurrent embodiment, the transparent conductive layer 0160 contains amaterial selected from the group consisting of indium tin oxide (ITO),indium zinc oxide (IZO), Al-doped ZnO (AZO), fluorine-doped tin oxide,and a combination thereof.

In the current embodiment, the vehicle electronic rear-view mirror 0100could be optionally provided with the electrical connector 0170. Forinstance, in an embodiment, the electrical connector 0170 could be aconducting wire or a conducting structure electrically connected to thetransparent electrode 0150 and the reflective layer 0190, so that thetransparent electrode 0150 and the reflective layer 0190 could beelectrically connected to the at least one control member 0180, whichprovides a driving signal via the conducting wire or the conductingstructure, thereby driving the electro-optic medium layer 0140.

When the electro-optic medium layer 0140 is enabled, the electro-opticmedium layer 0140 would undergo an electrochemical redox reaction andchange its energy level to be in a diming state. When external lightpasses through the opening of the casing 0110 and reaches theelectro-optic medium layer 0140, the external light would be absorbed bythe electro-optic medium layer 0140 which is in the diming state, sothat the vehicle electronic rear-view mirror 0100 is switched to ananti-glare mode. On the other hand, when the electro-optic medium layer0140 is disenabled, the electro-optic medium layer 0140 is transparent.At this time, the external light passing through the opening of thecasing 0110 passes through the electro-optic medium layer 0140 to bereflected by the reflective layer 0190, so that the vehicle electronicrear-view mirror 0100 is switched to a mirror mode.

More specifically, the first transparent assembly 0120 has the firstincidence surface 0122 which is away from the second transparentassembly 0130. For instance, external light from the rear vehiclesenters the vehicle electronic rear-view mirror 0100 via the firstincidence surface 0122, and then the vehicle electronic rear-view mirror0100 reflects the external light such that the external light leaves thevehicle electronic rear-view mirror 0100 via the first incidence surface0122. In addition, eyes of the vehicle driver could receive the externallight reflected by the vehicle electronic rear-view mirror 0100 to knowthe position of other vehicles behind. Moreover, the reflective layer0190 could have the optical property of partial transmission and partialreflection by selecting a suitable material and designing a proper filmthickness.

The display of the vehicle electronic rear-view mirror 0100 could be anLCD or an LED, and the display could be disposed inside or outside thecasing 0110, for example, on the side of the second transparent assembly0130 away from the first transparent assembly 0120, or on the secondexit surface 0134 of the second transparent assembly 0130 away from thefirst transparent assembly 0120. Since the reflective layer 0190 has theoptical property of partial transmission and partial reflection, theimage light emitted by the display could pass through the reflectivelayer 0190, thereby allowing the user to view the internal imagedisplayed by the display so as to display the warning message.

In the current embodiment, the movable carrier auxiliary system 0001further includes a global positioning device 0025 and a road map unit0026 which are disposed in the movable carrier 0000 and are electricallyconnected to the operation module 0013. The global positioning device0025 continuously generates and outputs a global positioninginformation. The road map unit 0026 stores a plurality of roadinformation, wherein each of the road information contains at least onesign information, and could be a map of each of a plurality of roads. Acertain loca of the map of each of the roads has the at least one signinformation (e.g. an appearance of the sign, a content of an instructionof the sign, etc.). The operation module 0013 continuously receives theglobal positioning information and continuously compares the roadinformation, thereby to find one of the road information correspondingto the global positioning information at that time. The operation module0013 then captures the at least one sign information of thecorresponding road information corresponding to the global positioninginformation at the time, and correspondingly determines whether theenvironment image has a sign image that matches at least one of the signmodels, and correspondingly generates a detection signal. In this way,the correctness of the detected sign image could be determined via theenvironmental image and the sign information of the road information.

The movable carrier auxiliary system 0001 further includes an updatemodule 0027 electrically connected to the road map unit 0026, the globalpositioning device 0025, and the storage module 0012, wherein the updatemodule 0027 could update following information.

The update module 0027 could obtain a region or a country that themovable carrier 0000 locates based on the global positioninginformation, and correspondingly update at least one of the roadinformation stored in the road map unit 0026 and/or could update atleast one of the sign information.

The update module 0027 could update at least one of the sign models. Inaddition, the update module 0027 could obtain a region or a country thatthe movable carrier 0000 locates based on the global positioninginformation, and correspondingly update at least one of the sign modelsstored in the storage module 0012.

In the current embodiment, the sign detecting device 0010 furtherincludes an information receiving device 0016 electrically connected tothe operation module 0013, wherein the information receiving device 0016is adapted to receive at least one sign information (e.g. a content ofthe sign information is speed limit of 60 Km/h) outputted by a controlcenter or a traffic sign in a wireless manner. The operation module 0013determines whether the environment image has a sign image that matchesat least one of the sign models via the at least one sign information,and correspondingly generates a detection signal, thereby to determinethe correctness of the detected sign image via the environmental imageand the sign information received by wireless communication.

The storage module 0012 further stores a plurality of sign categories,and each of the sign categories has the sign models, wherein the signcategories could include a warning sign, a prohibition sign, anindication sign, an auxiliary sign, and etc. Each of the sign categorieshas at least one kind of sign models. The operation module 0013correspondingly analyzes the sign category of the matching sign modelafter determining whether the environment image has a sign image thatmatches at least one of the sign models, and generates a detectionsignal based on an analysis result of the operation module 0013.

In addition, the operation module 0013 could be electricallyconnected to a prompting member 0029 of the prompting device 0028, sothat the prompting member 0029 could correspondingly generate a voicesound to the movable carrier 0000. For instance, the prompting member0029 prompts that the speed limit is 60 Km/h via the voice sound when asign that the speed limit of 60 Km/h is detected.

FIG. 1F is a schematic view showing a surrounding carrier 000D islocated in front of the movable carrier 0000, wherein the sign on thesurrounding carrier 000D is a brake light 000D1 as an example.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the optical image capturing system, and the glass lenses maycontrol the thermal effect and enlarge the space for arrangement of therefractive power of the optical image capturing system. In addition, theopposite surfaces (object-side surface and image-side surface) of thefirst to the seventh lenses could be aspheric that could obtain morecontrol parameters to reduce aberration. The number of aspheric glasslenses could be less than the conventional spherical glass lenses, whichis helpful for reduction of the height of the optical image capturingsystem.

Furthermore, in the optical image capturing system provided by thepresent invention, when the lens has a convex surface, it means that thesurface of the lens around the optical axis is convex, and when the lenshas a concave surface, it means that the surface of the lens around theoptical axis is concave.

The optical image capturing system of the present invention could beapplied in a dynamic focusing optical image capturing system. It issuperior in the correction of aberration and high imaging quality sothat it could be allied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module could be coupled with the lenses to move the lenses. Thedriving module could be a voice coil motor (VCM), which is used to movethe lens for focusing, or could be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the seventh lens of the optical image capturing system of the presentinvention could be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect could be achieved by coating on atleast one surface of the lens, or by using materials capable offiltering out short waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing system in the present invention could be either flat orcurved. If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane could be decreased, which is not only helpful to shorten thelength of the optical image capturing system (TTL), but also helpful toincrease the relative illuminance.

As shown in FIG. 3A and FIG. 3B, an optical image capturing system 20 ofthe second optical embodiment of the present invention includes, alongan optical axis from an object side to an image side, a first lens 210,a second lens 220, a third lens 230, an aperture 200, a fourth lens 240,a fifth lens 250, a sixth lens 260, a seventh lens 270, an infrared raysfilter 280, an image plane 290, and an image sensor 292.

The first lens 210 has negative refractive power and is made of glass.An object-side surface 212 thereof, which faces the object side, is aconvex spherical surface, and an image-side surface 214 thereof, whichfaces the image side, is a concave spherical surface.

The second lens 220 has negative refractive power and is made of glass.An object-side surface 222 thereof, which faces the object side, is aconcave spherical surface, and an image-side surface 224 thereof, whichfaces the image side, is a convex spherical surface.

The third lens 230 has positive refractive power and is made of glass.An object-side surface 232, which faces the object side, is a convexspherical surface, and an image-side surface 234, which faces the imageside, is a convex spherical surface.

The fourth lens 240 has positive refractive power and is made of glass.An object-side surface 242, which faces the object side, is a convexspherical surface, and an image-side surface 244, which faces the imageside, is a convex spherical surface.

The fifth lens 250 has positive refractive power and is made of glass.An object-side surface 252, which faces the object side, is a convexspherical surface, and an image-side surface 254, which faces the imageside, is a convex spherical surface.

The sixth lens 260 has negative refractive power and is made of glass.An object-side surface 262, which faces the object side, is a concaveaspherical surface, and an image-side surface 264, which faces the imageside, is a concave aspherical surface. Whereby, the incident angle ofeach view field entering the sixth lens 260 could be effectivelyadjusted to improve aberration.

The seventh lens 270 has negative refractive power and is made of glass.An object-side surface 272, which faces the object side, is a convexsurface, and an image-side surface 274, which faces the image side, is aconvex surface. It may help to shorten the back focal length to keepsmall in size, and may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The infrared rays filter 280 is made of glass and is disposed betweenthe seventh lens 270 and the image plane 290. The infrared rays filter280 gives no contribution to the focal length of the optical imagecapturing system 20.
